Haha, how did I know it was gonna be "wrought iron like"? Looks cool, man. Checked out royalgates.net . Cool biz, is that yours?
If your refering to the spade looking tabs, you buy them already punched. The materials cost is pretty low, I would say about $8.00. I could have it powder coated too for about $5.00 (I know the owner) but it's only a battery tray to me. Besides, the angle that I used was powder coated anyway. I'm the king of scraps, LOL
